Tips: Line number and accuracy of servo motor encoder

Nowadays, many people think encoder has higher line number, then servo motor control accuracy would be higher, this leads to some people simply thought the poor equipment accuracy issue can be solved by using servo motor with high line number encoder. With mark line showing 10000, this is an ignorant pursuit, pay high cost for this encoder, it might be not helpful, instead it might bring much trouble.
Encoder type should match the property of servo motor. Mark line of DC servo motor encoder should match groove number of DC motor. Mark line of AC servo motor encoder should match the pole number and phase number of AC servo motor. The purpose is mark line is the integral multiple of motor stepping, in the case, inspection signal of code would be integer, no decimal, no deviation. Refer to incremental type and absolute type encoder, the difference is incremental type only has second hand, the same as the timer without minute hand and hour hand.
The main function of encoder is to check servo operation step, revolution, can output the information for actual operation, i.e. origin position, steering etc. The system purpose is accurate control for the driven work piece position, displacement and speed. The control accuracy is unrelated with encoder mark line, as long as encoder can accurately detect the steps.
